16. USB, Infrared, PS/2 Mouse Module Connector (USB/MIR, 18-1 pins)
If you want to use USB, PS/2 mouse, or infrared (IrDA) devices, you need to
purchase an external connector set. The external connector set connects to the
18-pin block and mounts to an open slot on your computer’s chassis. The system
will direct IRQ12 to the PS/2 mouse if one is detected. If not detected, expan-
sion cards can use IRQ12. See PS/2 Mouse Control in BIOS Features Setup
and USB Function in PnP and PCI Setup of the BIOS SOFTWARE. See Sec-
ond IrDA... connector for details on the infrared connector.
